What I claim, therefore, and desire to secure by Letters Patent is:

1. Road surface treating equipment comprising a wheeled vehicle having a road trav' ersing member, a plurality of scarifying bars depending substantially vertically therefrom in laterally spaced relation terminating at their lower ends in road way grooving broad edged teeth, a reservoir for holding road treat-ing fluidmounted on said vehicles, and a conduit fixed to each of said bars at its rear face and depending therewith to a lower terminal discharge point above its lower toothed end, the upper end of each conduit having communication connection with said reservoir.

2. Road surface treating equipment comprising a wheeled vehicle having a road traversing member, a plurality of road surface scarifying bars depending substantially vertically therefrom in laterally spaced relation with their lower ends having broad front faces forwardly curved and terminating in broad edged, road grooving teeth, a reservoir for holding road treating fluid mounted on said vehicle, a conduit fixed to the rear face of each of said bars and depending therewith to terminate at a fluid discharge point at the rear of and above its grooving tooth, the lower discharge end of said conduit inclining upwardly and rearwardly, a tank for road treatment fluid mounted on and travcrsing the vehicle, a traversing trunk conduit supported substantially below said tank and having a fluid conduit in communication therewith, the upper ends of said bar-fixed conduits having communicating connection with said traversing trunk to receive Huid therefrom.
